Title: Display device of cumulative run hour of excavator
Inventor: YAMAGUCHI TAKESHI
IPC: G04F10/00
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To reduce an error and suppress useless power consumption by measuring and accumulating run hours only when a power switch is ON and the detection signal of the operation of an excavator is being outputted. SOLUTION: An operation judging means 6a of an operation part 6 judges the presence or absence of the input of the detection signal of an engine start detection device 3 when a power switch 2 is turned on and an operation means 6b measures run hours from the input of the detection signal. An operation means 6c adds the run hours to the cumulative run hour stored at a storage part 7 until the power switch 2 is turned on. An output part 8 outputs the cumulative run hours stored at the storage part 7 to a display part 9a according to the judgment of the operation judging means 6a or continue the output and outputs a value obtained by the operation means 6c to a display part 9b as second cumulative run hour, thus displaying the cumulative run hours with less error and properly judging the maintenance period.
